Metal-diamond sinters are composites which are obtained by powder metallurgy method. Correct choice of chemical composition of matrix, diamensions and concentration of diamond particles result in obtaining properties suitable for application of sinters. Matrix components are Co, Ni, WC, Cu, Dn, W and others. Applied diamond particles are synthetic and natural, mainly imported, with high technological properties. The metal-diamond segments are mainly used for cuting: marble, granite, concrete, sandstones and asphalt.
